Hey All, we have a production server that recently started generating ABMicroLogixReadRequest errors just about every minute, followed by a clock drift. I wondered if anyone had seen anything like this before? I do have a ticket open but thought perhaps someone else had seen this before and could provide some info on the resolution. The interesting thing is this gateway supports about 100 perspective clients, and we see no outages or any other detrimental effects from this issue at the present time.
I would suspect the driver timeouts are a side effect of your clock drifts. (Actual response was likely lost during a pause-the-world GC event.) Investigate your GC performance. Probably by turning on GC logging.
